COVID-19 Research Results Published in Radiology

On March 20, the research results of Keya Medical’s COVID-19 AI Assisted Diagnosis algorithm were published in the peer-reviewed journal Radiology.


Aims to accurately detect COVID-19 and differentiate it from Community-Acquired Pneumonia (CAP) and other lung diseases.

Powered by cutting-edge artificial intelligence and medical image analysis technologies, DEEPSCAN helps radiologists diagnose and assess pneumonia progress efficiently.

CT Pneumonia Detection Workflow

Worklist – Triage and Notification

Real-time lung CT images analysis

Automated detection of COVID-19 and differentiation from other types of pneumonia

Radiologists can choose their review priorities based on notifications on the worklist

Improve the efficiency of detecting COVID-19 or other pneumonia suspected patients

Image Analysis


Detection Results

  • Suspected COVID-19
  • Suspected Pneumonia
  • No inflammation identified

QA in Lung Lobes

  • Schematic diagram of infected regions
  • Quantitative assessment of lesion volume and lesion proportion

Lesion Histogram

  • Hounsfield unit (HU) distribution within lesion regions
  • Lesion volume and proportion grouped by different HU ranges


  • Summary of findings in each lobe for direct use: lesion volume, proportion, and characteristics (GGO, consolidation)

Lesion Segmentation

Automated lesion contouring for lesion identification and quantitative analysis
Multiplanar observation (Transverse/Coronal/Sagittal)
Draggable scrollbar for fast lesion localization

Follow-Up Comparison

Comparing two consecutive scans of the same patient quantitatively to assess the progress of pneumonia
Linking slices of the lungs from two consecutive scans for convenient observation and comparison
Changes in lesion proportions of each lobe are compared and shown using arrows (showing increased/decreased trend)


Clinical Datasets

Retrospective multi-center clinical validation


CAP and non-pneumonia patients were randomly selected (Aug 16, 2016 – Feb 17, 2020)


Avg Age: 49 Male: 1838 Female:1484

CT Scans

COVID-19: 1296 CAP: 1735 Other: 1325

COVID-19 Scans

Acquired between Dec 31, 2019, and Feb 17, 2020 All were confirmed by RT-PCR

Workflow & Methods

COVID-19 detection neural network – COVNet: based on deep neural network, AI-powered

  • Input: CT DICOM (Non-contrast CT, Slice thickness<=3mm)
  • Output: Disease Classification Labels (COVID-19, CAP, Non-Pneumonia)
